How many social security numbers are available if the only restriction is that the number 000-00-0000 cannot be assigned?

1 answer:

3 0

Each digit can be 0-9 ( 10 numbers)
there are 9 numbers in a social security number

multiply 10 nine times:
10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000,000 ( 1 billion) possibilities.

the restriction is it can't be all zeros so subtract 1 from the total
1,000,000,000 - 1 = 999,999,999 combinations

George and Carmen went on a bicycle trip. They took a bus to their starting point and then biked the rest. They traveled 350 kil

Total distance covered by George and Carmen
x + y = 350
And they biked 80 kilometers more than they bussed
80 + y = x 
Putting the value of x=80 + y in x + y = 350:
We get:
80 + y + y = 350 
2y = 270 
y = 135 km

Substituting y = 135 in x + y = 350 
x + 135 = 350
x = 215 km 

Thus George and Carmen biked for 215 km and bussed for 135 km.

Answer:

See attached graph

Step-by-step explanation:

The equation is y-3=(x + 6)

Write the equation in a slope intercept form, then graph the equation on a graph tool to see the points that line on the line.

Alternatively , using the coordinates in the answer choices given, input them in the equation of the graph and select the answer choice that has all its coordinates true to the equation.

y-3 = x+6 -----can be written as : y= x+9

Graph y= x+9 to see the graph and the points that are on the line as attached.
